Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Lower protector before well card of this embodiment contains preceding lower protection crossbeam 1, left side reinforcing plate 4, right side reinforcing plate 5, left linking bridge 2 and right linking bridge 3 and installs in the blanking cover 6 at preceding lower protection crossbeam 1 both ends. The front lower protective crossbeam 1, the two reinforcing plates and the two connecting supports are all connected in a welding manner, and the front lower protective crossbeam 1 and the blanking cover 6 are fixed by adopting a cross-shaped groove pan head self-tapping screw.
The front lower protective crossbeam 1 in this embodiment is formed by bending a Q235 steel plate integrally, and includes a protective plane 11 and a pair of hollow rectangular pipes 12 formed by bending and rolling back along two sides of the protective plane, and a predetermined interval is provided between the two hollow rectangular pipes 12. The cross section of the front lower protective beam 1 is of a concave hollow closed structure, the wall thickness of the front lower protective beam is 2mm, the length of the front lower protective beam is 1952mm, the width of the front lower protective beam is 60mm, the height of the front lower protective beam is 120mm, and the bending fillet is R7. The front lower protective crossbeam 1 is transversely arranged at the front end accessory of the frame, and the left side and the right side of the crossbeam are provided with the blocking covers 6.
The left reinforcing plate 4 and the right reinforcing plate 5 in the embodiment are formed by bending steel plates with the wall thickness of 3mm, the bent sections of the left reinforcing plate and the right reinforcing plate are concave matched with the front lower protective cross beam 1 and comprise a plane part 7 and bent arm wrapping parts 8 on two sides, the plane part 8 is attached to the back of the front lower protective cross beam, and the two bent arm wrapping parts 8 are respectively wrapped and attached to the outer side surfaces of the two hollow rectangular tubes; one side of each reinforcing plate is welded on the back side of the front lower protective cross beam 1, and the other side of each reinforcing plate is welded with the two connecting supports as the connecting planes of the left connecting support 2 and the right connecting support 3.
Left linking bridge 2 in this embodiment is the same with right linking bridge 3's structure, adopts an L type right-angle board and welds the angle seat structure that forms at two set-square splice welding of L type right-angle board both sides respectively, and the wall thickness of this angle seat structure is 5mm, the first plane of angle seat structure (the one side of L type right-angle board promptly) welds with the reinforcing plate, and the second plane of this angle seat structure (the another side of L type right-angle board promptly) is through bolt and one-level installing support assembly fixed connection of marking time.
According to the middle clamp front lower protection device, the cross section of the front lower protection beam is of the concave structure, and compared with the traditional rectangular structure, the middle clamp front lower protection device is higher in deformation resistance after being subjected to impact force. Because the force of the installation and fixing position is larger when the installation and fixing position is impacted, a reinforcing plate is welded between the left connecting bracket, the right connecting bracket and the cross beam so as to ensure the strength requirement of the installation position. In order to improve the protection performance of the front lower protection, the utility model also optimizes the configuration on the selection of the structural shape and the size, and through the optimization of the structures of all parts and the connection among the parts at the preset welding positions, the impact resistance strength of the front part and the left and right sides of the front lower protection can be greatly improved on the whole.
In summary, although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the utility model.
